MSDS (Material Safety Data Sheet) Answer: a standard information sheet for a
substance includes information about risks , disposal , spills and enviormental risks
what is a safe way to smell thing in a lab Answer: wafting
wafting Answer: pass or cause to pass easily or gently through or as if through the air
over a test tube to smell
HOw to properly dispose of chemicals Answer: never put in the sink or back into
container because of cross contamination. USE A WASTE DISPOSAL CONTAINER
when should you wash hands in lab Answer: before and after lab
what should you always wear in lab Answer: eye googles
what to do if their is a problem Answer: notify the teacher
chemicals must always be what in a lab Answer: labeled
what must you always have for every chemical in a lab Answer: a msds sheet
Parts of a microscope Answer: eyepiece, objective lens, fine adjustment know, course
adjustment knob, stage, stage clips, diaphragm
How to carry a microscope properly Answer: one hand underneath the bottom and one
hand on the arm and always cover back up
what is a fume hood for Answer: it pulls chemical gas up and away from people
who regulates labe saftey Answer: osha
data table Answer: an arrangement of data in which each row represents a case and
each column represents a variable, numerical quanititaive data, time frequencies
bar graph aka histogram Answer: compares amount of something in different catefores
especially in qualitative data
histograms aka bargraphs Answer: set up the same as bargraphs but express data in
quanitiave
pie charts Answer: represent data that is part of a whole. best used in compariason of
data apart of a whole

, statistics Answer: futher analyse large amounts of data to describe and make
inferences bout
patterns Answer: similar or repeated sequences of data
trends Answer: data that moves in a gneral direction over the course of its collection
lie graphs and scatter plots Answer: she relationships between variables usually shows
quanatative data
quanitative data Answer: numerical data
qualitative data Answer: Information describing color, odor, shape, or some other
physical characteristic
when using line graphs the independent variable goes on which axis Answer: the x axis
because it is the one being manipulated
which axisi does the dependent variable go on in a line graph Answer: the y (up and
down axis) it depends on the independent variable
the y axis Answer: the vertical axisi that goes up and down
the x axis Answer: the axis that is horizontal and goes sideways
error analysis Answer: Mistakes on an individual's assessment are noted and
categorized by type
there are two types of errors in science Answer: 1.systematic error-errors that stem
from flaw in the data collection
2.random errors-caused by unpredicatble changes such as imprecise measurement
error analysis Answer: calculates the percent error observed in an experiment which is
done by calculating the scientists results to an established value . 10 %or less is
generally considered acceptable
three types of models in scientific models Answer: 1.physical models
2.conceptual models
3.mathematical models
physical models Answer: are physical copies of a phenomena that are built to scale
and are used to physically visualize processses and phenomena
conceptual models Answer: used to provide vivual representation of abstract concepts
mathematcal models Answer: mathematicla models are used to describe and predict
behavior or phenomena such as poulation growth
